Borrowing from a Oghur language, before the times of the Hungarian conquest of the Carpathian Basin (at the turn of the 9th and 10th centuries)[1], from Proto-Turkic*daŕ(“bald”). Cognates include Turkishdazlak(“bald”), Karakhanidتازْ‎ (tāz, “bald”), and Middle Mongolian[script needed](tarasun, “bald”), the latter perhaps a Turkic borrowing too.
